Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1 to 4, the present embodiment provides a punching device for a copper bar insulating sheath, which includes a rotating screw 1 and a sleeve 2 made of stainless steel.

The rotary screw 1 comprises a front section 11, a middle section 12 and a tail section 13 which are connected in sequence. The front section 11 is provided with threads; the tail section 13 is connected with a rotating handle; the middle section 12 is the smooth body of rod, and rotatory screw rod 1 passes sleeve 2 along sleeve 2's axial, and the clearance of the middle section 12 distance sleeve 2 inner wall of rotatory screw rod 1 is 0.5 ~ 1mm generally, and this example adopts 0.5 mm. Specifically, the front section 11 has a diameter of 4mm and a length of 5.5 mm; the diameter of the middle section 12 is 3.7mm, and the length is 46 mm; the tail section 13 has a diameter of 3mm and a length of 12 mm.

The front end of the sleeve 2 is provided with a knife edge 21, and the front end is nested in the outer ring of the front section 11. The outer diameter of the sleeve 2 is 11.5 mm. The length of the sleeve 2 is greater than the length of the middle section 12 of the rotary screw 1 and less than the total length of the middle section 12 and the front section 11, specifically 50mm, wherein the length of the knife edge 21 is 4 mm.

The knife edge 21 is an annular knife edge, and the diameter of the annular knife edge is generally 2-2.5 times of the diameter of the middle section 12. In this example, the diameter is 10.5mm and the facet is 0.1mm (as shown in FIG. 5). The knife edge 21 is made of tool steel. The outer ring of the sleeve 2 is also provided with anti-slip lines, so that the device can be conveniently held when in use.

The rotating handle comprises a rotating nut 31 and a locking nut 32, threads are arranged on the tail section 13 of the rotating screw rod 1, and the rotating nut 31 and the locking nut 32 are sequentially screwed in the threads and are installed on the tail section 13. The rotating nut 31 is further provided with a biasing hole 33 for biasing the rotating handle with a tool such as a screw driver when the device is used.
